Question

A town map has a scale of 2cm:0.5km what is the actual distance for a walk measured at 9cm on the map?

Answer 1

2.25 km

Explanation:

Since 2 cm represents 0.5 km on the ground we cross multiply to find how much ground will be represented by 9 cm on the map

1. 2cm=0.5km

9cm=?

• (9cm×0.5km)÷2cm

• 4.5km(cm)÷2cm
• 2.25 km

NOTE: since the cm are the same they will cancel each other out in the division stage

Answer 2

Answer: 2.25 km

Explanation:

2 cm = 0.5 km

9 cm = (9 x 0.5)/2

= 2.25 km
